"Telecom Commission discussed the matter (spectrum usage charge) but it needs further deliberations. There will be another meeting next 2-3 days for further discussion," a government official said after the meeting.

Telecom Regulatory Authority of India (TRAI) had in September recommended levying a uniform spectrum usage charge (SUC) of three percent of the revenues earned by mobile operators from April 1, 2014 and keeping the upper limit of SUC at five percent.

Levied annually by the government, SUC varies from three-eight percent for mobile service providers and one percent for holders of broadband wireless access (BWA) spectrum that can be used for 4G services.

The uniform SUC, if implemented as recommended by TRAI, will provide relief to mobile operators such as Airtel, Vodafone and Idea but will increase rates for BWA spectrum holders including Reliance Jio Infocomm Ltd (RJIL).

"Telecom Commission will look at exploring additional options for a revenue neutral regime," the source said.

The panel is learnt have worked out six SUC scenarios and their probable revenue impact on the exchequer. While GSM players like Airtel, Vodafone, Idea Cellular and Uninor have been demanding implementation of uniform SUC, RJIL has opposed any such move.
